I found some aquatic plants today. I thought it was anacharis until I picked them up. the leaves are smaller and more pointy and grow closer together, but the stems and the way it grows looks very close to anacharis. Can anyone identify it?All of them together in water. You can also see some of the roots in this one.

A single one

A smaller one

What the top looks like from above.

None of the leaves are larger than the two I had on my fingers and the roots were very easy to pull up if that can help to identify it. Also it has been in the
26-30F outside and this plant is growing in a pond.

that kind of looks like the fine leafed hornwort....the wife and i were talking about it the other day...not sure if it's a different variety or it just different due to growing conditions relative to light , tank chemistry etc....
